Patch looks fine.  I'll check it in.

Just looking at the surrounding code, I wonder why we return -EPERM
for the default case?  EINVAL would possibly be a better choice for a
generic "something went wrong".

How are we progressing towards having something that could be sent
upstream (as far as the hvc stuff is concerned)?
